I haven’t had this problem, but I will do some idle speculation. My Schwinn is
about 15 years old and my wife’s is from the same era. The bearings on both of
them freely slide sideways along the axle but neither one wobbles. I wonder if
you just may need new bearings. You can get them from the Unicycle Factory
(see FAQ).

I’ve never mey a schwin, so I dont know it’s construction. However, if the
problem is that the bearings are loose on the axel, you could try pulling them
off then shimming with a thin sheet of metal. Just wedge a collar of the metal
round the shaft before forcing the bearings back on. Soft drinks cans are
excellent - although the steel ones may work better than the aluminium.
